PORTABLE GROUND STANCHION USABLE A$ A STRAINEB POST.

Application filed March 15, 1928, Serial No. 251,931, and in AustraliaMarch 21, 1927;

' This stanchion consists "of a T section steel;

stud adapted to be driven into the ground, with strut feet pivotallyhung 1n a slider which runs on the stud and is clamped to the stud byinward pressure of the strut ends when the struts are extended. vA stayis pivotally fixed at one end of it on one of the strut feet with itsother end adapted to engage serrations cut in the edge of the web of thestud. The strut feet arefoldable back on the stud, thus to minimizespace; when so folded two or more complete st-anchions may be nestedendfor-end and wrapped or rolled within canvas sheet which may be usedas a stretcher, mattress, hammock or sunshade, and carried on therunning board of a car or otherwise.

The features of a ground stanchion according to the invention areillustrated in the drawings in which Fig. 1 is a perspective view of acomplete stanchion in use as a support suspending one end of a hammockbed; it also suggests its use as a strainer post for a wire fence;

Fig. 2 shows the stanchion folded up for packing;

Fig. 3 is a section on the line 33, Fig. 1

it shows the preferred section of the strut feet; and

Fig. 4 is a detail perspective view on enlarged scale of the slider; itis explanatory of the punching action of the ends of the strut feet whenthey are extended at right angles to the stanchion stud.

The stud 10 is in practice always of T section; but it might be of Z,channel, L, cruciform,.or other angle section. Its bottom end i 11 issharpened to facilitate driving into the ground. ment with the web 13 ofstud 10, and 14 and to, aligning respectively withthe two flanges of thestud 10. The three strut feet 12, 14; and 15 are constructed of stripsheet folded to form a T section; they are carried by a slider 16 whichis most readily built up of a flat back .piece and two angles which areunited by three rivets or bolts 17 which form pivots for the strut feet12, 14 and 15 respectively. When the strut feet are extended to theright angle position as seen in Figs. 1

12 is a strut foot which is in align-.

at their outer ends by staples 22 which are.

driven into theground through holes in their flanges.

at W e.

The Web 13 of the studlO is drilled with holes 18 for theattachmentoffence wires or the like to itand nearits top end it isangu-,

larly serrated. A stay bar 19 of channel sec tion is pivotally fixed at20 on the strut foot 12; its top end is engageable with the serrations21. When set up the stay bar is secured against accidental displacementby a wire loop 23 which is passedthrough a hole in it o touches theground, the strut feet spreading I apart till they rest on the groundfor their full length. The staples 22 are then driven I into the groundto provide a firm anchorage for the strut feet which hold the stud 10against lateral angular displacement. The slider 16 is securely clampedto the stud by the pinching engagement of the ends of. the strut feetwith the edges of the stud and any attempt to draw the stud withoutfirst removing the staples 22 will only serve to more securely bind thestud in the grip of the slider due to the knuckle action of the ends 24of the strut feet. If the stanchion is to be used as a strainer post forfencing wire, the wire ends are looped through the holes 18. asindicated at 30, Fig. 1. V When it is desired to use the stanchion as asupport for one end .of a canvas bed or pin 35 which is set in a hole18, and a tensioning screw 40 carries the strainer legs 32 and bears onthe back of the flange of the stud 10. 37 are guy wires or cordsfastened to the ends of the swingle bar 33 and looped through grip loops38 formed'of bent wire which are hung on the ends of the strut feet 14and 15. r r v To remove the stanchion, the ground staples 22 are priedup by means of a tool, and

the strut feet then tippedup thus to release theirclamping grip on thestud. I The stud may then be drawn.

The essential feature of the invention is a slidercarrying the innerends of strut feet pivotally, with the ends of the strut feetdriven intothe ground, a slider adapted for vertical movement along said stud,three jaws in said slider in 90 relation, ground struts of angle sectionand pivoted in the respective jaws of the slider with their pivoted endsshaped to engage with and bind on the stud when the struts are spreadhorizontally and to clear the stud when the struts are in angularrelation to the stud, and a stay pivotally fixed at its bot-tom end toone of said struts and adapted to be engaged at its top end with edgenotches in the stud, said stay bent to overlie the slider when theground struts are collapsed and nested parallel with the stud.

2. A ground stanchion according to claim 1, having the stud and thestruts of T section and having drive anchors associated with the struts.

3. A ground stanchion according to claim 1, having the stud and thestruts of T section, and the stay of channel section, with a loop hungon the stay to embrace the stud and adapted to hold the stay end inengagement with the notches in the stud.

In testimony whereof I affix my signature. CARLTON CLAYTON.
